General Electric recently introduced a wind turbine equipped with a storage battery, creating a type of “hybrid” turbine that industry leaders hope will improve the integration of intermittent energy sources onto the grid and reduce the costs of wind power. (more…)

One of the major trends in wind power is ever larger turbines for offshore use. This raises many technical challenges, including how to transport and install such large components at offshore sites.

A2SEA is a Danish company that has expertise in precisely these challenges and has developed technology for it. The company’s Sea Installer is a (more…)

A new study concludes that it would be technically and economically feasible for New York State to meet all of its energy needs from renewable sources by 2030, but researchers say the transition would involve building wind, solar, and other alternative energy sources on a mass scale. (more…)

There’s a compelling and thought-provoking book making the rounds called Clean Tech Nation that should make its way to your must-read list this Fall.

Authored by Ron Pernick and Clint Wilder, the thrust of the book is that the U.S.—long a leader in various technological revolutions—is falling behind the rest of the world when it comes to clean technology (more…)

The UK’s Advertising Standards Authority (ASA) recently shut down an anti-wind power ad run by the Trump Organization and Communities Against Turbines Scotland on the grounds that the picture and text of the ad were misleading (see the Treehugger piece here).

The ad (reproduced below) said “Welcome to (more…)

Given the opportunity to work with some of the brightest minds in the cleantech industry who are creating everything from micro hydroturbines to small, lightweight, three-wheeled electric cars, I’ve learned that bigger is not always better. Yet in the case of a new wind power innovator, their approach has been to go big – in this case, tall – or go home. (more…)

Everyone is seeking the elusive killer app that will revolutionize energy. Most expect it to be a high tech gadget, or new form of generation or a way to finally store mass quantities of electricity.

Not anthropologist Susan Mazur-Stommen. She’s looking in a completely different place: inside our (more…)

Most people would agree that developing clean, renewable sources of energy is an ecologically sound proposition. The images of pristine power derived from the sun are inherently beautiful. But what if that new wind turbine is constructed of components that cannot be recycled? And what if that hydroturbine contains toxic materials that pollute (more…)

WindMade is a new certification label for companies that obtain at least 25% of their electricity from wind power.

Recently, Danish hearing aid manufacturer Widex became the first company in the world to receive the WindMade label. A wind turbine supporting 95% of Widex’s energy use, including production, put the company well above the percentage threshold (more…)

What a week!

At the start of the year we forecasted that one of the big trends in 2012 would be the return of the private equity markets to the fuel cell and hydrogen industry. In fact, this trend has been far larger and is now having an impact on the entire cleantech sector. (more…)
